Gameplay tactics on the large map.

Dark Elves, with the right approach, are a very dangerous opponent and are loved by many players. Play as them, master them, and you will love them too.

The problem is that when starting with a hero, you have very few resources and units. For example, I had 60 Dwarven Warriors stationed at the sawmill, and at the beginning, there are only enough resources to build Scouts (and possibly upgrade them) and Furies. After that, there is simply no more ore left, plus there are few mana wells on the map. Why Furies and not Megeras? I agree about spellcasting, knowledge, and so on; after all, this is the strongest race in terms of magic damage, and if you also have a lucky Mage and 325 mana... And how will "battle to the last" double the casting speed of Lightning and Ice Blocks? In general, the biggest problem that arose at the beginning was strong stacks of guards and a low number of units. And which hero should you choose for large maps, and why?
P.S. Medyan, don't think I'm a newbie, but I don't often play as Dark Elves, especially at such a high difficulty level, so I'm asking for advice. I know about elemental chains and artifacts, but all of this requires resources and experience.

There's simply no one and nothing to use. The end.

What about a faction hero for the "Hero" difficulty level, plus strong neutral creatures at the beginning of the game?
